completely irrelevant point of clarification: bank underground refers to the London Underground (metro station) stop immediately in front of the bank, rather than some sort of anarchist agenda (but given UK civil servants general ambivalence towards authority there may be a slightly sly nod to the alternative reading of this).
Although, there was at one point an anarchist organization called the weather underground: https://en.wikipedia.org/wiki/Weather_Underground I understand they had a "brick reallocation committee" that reallocated bricks through windows.
As objectionable as such behavior might be, I find the understated names pretty amusing.
